Geissele Automatics SMR MK4 M-LOK Free-Float Handguard Rail 9.3in Black 05-283B
Product Description
The Geissele Super Modular Rail (SMR) MK4 M-LOK is an ultra-lightweight, purpose-built free-float handguard designed to deliver a strong, rigid mounting platform with excellent heat management. Integrated short M1913 Picatinny rail sections at the fore of the rail in the 3, 6, and 9 o’clock positions provide ready-to-use mounting space, while maximum venting helps dissipate heat and reduce overall weight. Magpul M-LOK attachment points are provided at the 3, 6, and 9 o’clock positions as well as the upper 45-degree quadrants for a highly modular setup.
The SMR MK4 includes Geissele’s proprietary 2.25" long barrel nut to increase receiver interface surface contact for improved straightness, accuracy support, and zero repeatability during disassembly and reassembly. Installation requires a Geissele barrel nut wrench (sold separately).
